The survey provides a second inventory of native, non indigenous and cryptogenic marine species within the port and compares the biota with the results of an earlier port baseline survey of the Port of Nelson undertaken in January 2002. The survey is part of a nationwide investigation of native and non-native marine biodiversity in 13 international shipping ports and three marinas of first entry for yachts entering New Zealand from overseas. To allow a direct comparison between the initial baseline survey and the resurvey of the Port of Nelson, the survey used the same methodologies and sampled the same sites used in the initial baseline survey. To improve the description of the biota of the port, some additional survey sites were added during the repeat survey. Sampling methods used in both surveys were based on protocols developed by the Australian Centre for Research on Introduced Marine Pests (CRIMP) for baseline surveys of non-indigenous species (NIS) in ports. Modifications were made to the CRIMP protocols for use in New Zealand port conditions. These are described in more detail in the body of the report. A wide range of sampling techniques was used to collect marine organisms from habitats within the Port of Nelson. Fouling assemblages were scraped from hard substrata by divers, benthic assemblages were sampled using a sled and benthic grabs, and a gravity corer was used to sample for dinoflagellate cysts. Mobile predators and scavengers were sampled using baited fish, crab, starfish and shrimp traps. Sampling effort was distributed in the Port of Nelson according to priorities identified in the CRIMP protocols, which are designed to maximise the chances of detecting non-indigenous species. Most effort was concentrated on high-risk locations and habitats where non-indigenous species were most likely to be found. Organisms collected during the survey were sent to local and international taxonomic experts for identification. A total of 193 species or higher taxa were identified in the first survey of the Port of Nelson in January 2002. They consisted of 130 native species, 13 non-indigenous species, 20 cryptogenic species (those whose geographic origins are uncertain) and 30 species indeterminata (taxa for which there is insufficient taxonomic or systematic information available to allow identification to species level). During the repeat survey, 257 species or higher taxa were recorded, including 176 native species, 13 non-indigenous species, 32 cryptogenic species and 36 species indeterminata. Many species were common to both surveys. Around 48% of the native species, 54% of non-indigenous species, and 38% of cryptogenic species recorded during the repeat survey were also found in the earlier survey. The 13 non-indigenous organisms found in the repeat survey of the Port of Nelson included representatives of 5 taxanomic groups. The non-indigenous species detected MAF Biosecurity New Zealand Port of Nelson: Second baseline survey for non-indigenous marine species 1 were: (Annelida) Hydroides elegans; (Bryozoa) Bugula flabellata, Cryptosula pallasiana, Electra tenella, Celleporaria nodulosa, Watersipora subtorquata; (Hydrozoa) Lafoeina amirantensis, Filellum serpens?, Synthecium campylocarpum, Synthecium subventricosum; (Mollusca) Crassostrea gigas, Theora lubrica and (Macroalgae) Undaria pinnatifida. Six of these species - Hydroides elegans, Electra tenella, Filellum serpens?, Synthecium campylocarpum, Synthecium subventricosum and Undaria pinnatifida - were not recorded in the earlier baseline survey of the Port of Nelson. In addition, 6 non-indigenous species that were present in the first survey – Polydora hoplura (Annelida), Conopeum seurati, Electra angulata, Schizoporella errata, Anguinella palmata (Bryozoa) and Ciona intestinalis (Urochordata) – were not found during the repeat survey. Ten species recorded in the repeat survey are new records for New Zealand waters. Two of these were newly discovered non-indigenous species (a bryozoan, Celleporaria nodulosa, and a hydroid, Lafoeina amirantensis). The others are sponges that do not correspond with existing descriptions from New Zealand or overseas and may be new to science. The only species from the Port of Nelson on the New Zealand register of unwanted organisms is the Asian kelp, Undaria pinnatifida. This alga is known to now have a wide distribution in southern and eastern New Zealand. Most non-indigenous species located in the Port are likely to have been introduced to New Zealand accidentally by international shipping or spread from other locations in New Zealand (including translocation by shipping). Approximately 68 % (13 of 19 species) of NIS in the Port of Nelson are likely to have been introduced in hull fouling assemblages, 5 % (one species) via ballast water and 22 % (four species) could have been introduced by either ballast water or hull fouling vectors. One species (5%) is suspected to have arrived on drift plastic. The predominance of hull fouling species in the introduced biota of the Port of Nelson (as opposed to ballast water introductions) is consistent with findings from similar port baseline studies overseas. 2 Port of Nelson: Second baseline survey for non-indigenous marine species MAF Biosecurity New Zealand Introduction Introduced (non-indigenous)

    Invertebrate Responses to Large-Scale Change: Impacts of Eutrophication and Cataclysmic Earthquake Events in a Southern New Zealand Estuary A thesis submitted in partial fulfilment of the requirements for the degree of Doctorate of Philosophy in Ecology at the University of Canterbury, New Zealand Jennifer Erin Skilton 2013 Abstract Abstract Environmental stress and disturbance can affect the structure and functioning of marine ecosystems by altering their physical, chemical and biological features. In estuaries, benthic invertebrate communities play important roles in structuring sediments, influencing primary production and biogeochemical flux, and occupying key food web positions. Stress and disturbance can reduce species diversity, richness and abundance, with ecological theory predicting that biodiversity will be at its lowest soon after a disturbance with assemblages dominated by opportunistic species. The Avon-Heathcote Estuary in Christchurch New Zealand has provided a novel opportunity to examine the effects of stress, in the form of eutrophication, and disturbance, in the form of cataclysmic earthquake events, on the structure and functioning of an estuarine ecosystem. For more than 50 years, large quantities (up to 500,000m3/day) of treated wastewater were released into this estuary but in March 2010 this was diverted to an ocean outfall, thereby reducing the nutrient loading by around 90% to the estuary. This study was therefore initially focussed on the reversal of eutrophication and consequent effects on food web structure in the estuary as it responded to lower nutrients. In 2011, however, Christchurch was struck with a series of large earthquakes that greatly changed the estuary. Massive amounts of liquefied sediments, covering up to 65% of the estuary floor, were forced up from deep below the estuary, the estuary was tilted by up to a 50cm rise on one side and a corresponding drop on the other, and large quantities of raw sewage from broken wastewater infrastructure entered the estuary for up to nine months.

ABSTRACT. The mud whelk, Comine77a glandiformis, from the Avon-Heathcote estuary in Christchurch, is infected by three species of larval digenean parasite. The prevalence of infection in C. g7andiformis was found to increase with snail length for each parasite species. This introduced the possibility that gigantism could be occurring, and investigation of this formed the study basis. Differences were apparent between sexes of snail, and juvenile and adult individuals, with respect to both infection and position on the shore. For the analyses used, a combination of length and shell weight was found to be the most effective measure of snail size, but wet and dry tissue weights could also be used.

  • Equal Partnership: Two Trematode Species, Not One, Manipulate the Burrowing Behaviour of the New Zealand Cockle, Austrovenus Stutchburyi
    Journal of Helminthology (2004) 78, 195–199 DOI: 10.1079/JOH2003231 Equal partnership: two trematode species, not one, manipulate the burrowing behaviour of the New Zealand cockle, Austrovenus stutchburyi C. Babirat, K.N. Mouritsen and R. Poulin* Department of Zoology, University of Otago, PO Box 56, Dunedin, New Zealand Abstract Metacercariae of the trematode Curtuteria australis (Echinostomatidae) accumulate in the foot of the New Zealand cockle Austrovenus stutchburyi, severely impairing the cockle’s ability to burrow under the sediments. This results in increased predation by birds on cockles, and thus enhanced transmission rates of the parasite to its bird definitive hosts. This host manipulation by the trematode is costly: fish regularly crop the tip of the foot of cockles stranded on the sediment surface, killing any metacercariae they ingest. A second, previously undetected trematode species (characterized by 23 collar spines) co-existing with C. australis, has been found in the foot of cockles in the Otago Harbour, South Island, New Zealand. The relative abundance of the two species varies among localities, with the identity of the numerically dominant species also changing from one locality to the next. Both C. australis and the new species have a strong preference for encysting in the tip of the cockle’s foot, where their impact on the burrowing ability of the host is greatest, and where they both face the risk of cropping by fish. Results indicate that these two species are ecological equivalents, and their combined numbers determine

However, the assumption that shell shape variation is evidence of distinct lineages (species) might have led to taxonomic inflation within some gastropod lineages. Here, we compare shell shape variation and genetic structure of two independent lineages of New Zealand rocky shore whelks in order to understand the process that leads to an unusual disjunct distribution. We examined the Buccinulum vittatum complex (three subspecies plus Buccinulum colensoi) using mitochondrial DNA sequences, 849 single nucleotide polymorphisms and geometric morphometric data on shell shape. Specimens within the range of B. colensoi shared nuclear markers and mitochondrial DNA haplotypes with the southern subspecies Buccinulum vittatum littorinoides, whereas the northern samples (Buccinulum vittatum vittatum) had distinct genotypes.

  • Dispersal Ability, Habitat Characteristics, and Sea-Surface
    Baptista et al. BMC Ecol Evo (2021) 21:128 BMC Ecology and Evolution https://doi.org/10.1186/s12862-021-01862-1 RESEARCH Open Access Dispersal ability, habitat characteristics, and sea-surface circulation shape population structure of Cingula trifasciata (Gastropoda: Rissoidae) in the remote Azores Archipelago L. Baptista1,2,3,4*, H. Meimberg1, S. P. Ávila2,3,4,5, A. M. Santos4,6 and M. Curto1,7 Abstract Background: In the marine realm, dispersal ability is among the major factors shaping the distribution of species. In the Northeast Atlantic Ocean, the Azores Archipelago is home to a multitude of marine invertebrates which, despite their dispersal limitations, maintain gene fow among distant populations, with complex evolutionary and biogeo- graphic implications. The mechanisms and factors underlying the population dynamics and genetic structure of non- planktotrophic gastropods within the Azores Archipelago and related mainland populations are still poorly under- stood. The rissoid Cingula trifasciata is herewith studied to clarify its population structure in the Northeast Atlantic Ocean and factors shaping it, with a special focus in intra-archipelagic dynamics. Results: Coupling microsatellite genotyping by amplicon sequencing (SSR-GBAS) and mitochondrial datasets, our results suggest the diferentiation between insular and continental populations of Cingula trifasciata, supporting previously raised classifcation issues and detecting potential cryptic diversity. The fnding of connectivity between widely separated populations was startling. In unique ways, dispersal ability, habitat type, and small-scale oceano- graphic currents appear to be the key drivers of C. trifasciata’s population structure in the remote Azores Archipelago. Dispersal as non-planktotrophic larvae is unlikely, but its small-size adults easily engage in rafting.
